[0001] The utility model relates to the technical field of plastic housing processing, in particular to an automatic feeding machine for plastic housing processing. Background Technique

[0002] Plastic housings generally refer to the housings or shells made of plastic materials. These housings are widely used in various electronic devices, household appliances, computers and other products to protect internal components and ensure the normal operation of the devices. However, during the process of processing plastic housings, an automatic feeding machine is required.

[0003] In the Chinese patent document with the publication number CN215478403U, a feeding device for plastic product processing is disclosed, including a chassis, a material distribution plate and a support mechanism. The chassis includes a front end plate and a guide plate. The guide plates are symmetrically arranged on the rear end face of the front end plate and are vertically and fixedly connected to the front end plate. The material distribution plate is installed on the upper end of the front end plate and is rotatably connected to the front end plate. The support mechanism is installed on the upper end of the guide plate and is slidably connected to the guide plate. By means of a partition plate, it is ensured that the user can stably store different types of raw materials on the material distribution plate for use. At the same time, by installing a bent baffle on the partition plate, the safety of the raw materials during storage is ensured. When dumping is required, the user can remove the bent baffle storing the corresponding raw materials.

[0004] The deficiency of the above-mentioned disclosed solution is that when dumping raw materials, it is necessary to control the hydraulic cylinder to drive the material distribution plate to tilt, and then remove the bent baffle, resulting in relatively cumbersome operation, low automation degree, and reduced efficiency of dumping raw materials. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic feeding machine for plastic housing processing. By driving the rotary door to open while the feeding box is turned upwards, the automation degree is high, and the problems in the background technique can be effectively solved.

[0006] To achieve the above object, the utility model provides the following technical solution: an automatic feeding machine for plastic housing processing, including a feeding cart, a feeding box is arranged on the feeding cart. A support block is fixedly arranged at the bottom of the feeding box, and the support block is in contact with the feeding cart. Two symmetrically arranged fixing plates are fixedly arranged on the feeding cart, and a rotating component for driving the feeding box to turn is arranged on the two fixing plates. A rotary door is movably arranged on one side of the feeding box. A second rotating shaft is fixedly arranged on the rotary door, and the second rotating shaft is rotatably connected to the feeding box. The second rotating shaft passes through the feeding box and is fixedly sleeved with a second gear. A first gear is fixedly arranged on one of the fixing plates, and the first gear meshes with the second gear.

[0007] Furthermore, the rotating assembly includes a first rotating shaft, which is rotatably arranged between two fixed plates. A fixed block is fixedly arranged on the first rotating shaft, and the fixed block is fixedly connected to the bottom of the discharge box. A motor is fixedly arranged on one of the fixed plates, and the output end of the motor passes through the corresponding fixed plate and is fixedly connected to the first rotating shaft.

[0008] Furthermore, a rectangular frame is fixedly provided on the feeding trolley, a knocking block is provided on the sliding sleeve inside the rectangular block, a spring is fixedly provided between the knocking block and the rectangular frame, a connecting block is fixedly provided on one side of the knocking block, the first rotating shaft fixing sleeve is provided with a toggle wheel, and a plurality of toggle blocks are fixedly provided at intervals on the outer periphery of the toggle wheel, and the plurality of toggle blocks are respectively slidably cooperated with the connecting block to drive the knocking block to move downward.

[0009] Furthermore, the diameter of the first gear is greater than the diameter of the second gear.

[0010] Furthermore, the first gear is fixedly connected to the corresponding fixed plate via a fixed shaft, and the axis of the fixed shaft coincides with the axis of the first rotating shaft.

[0011] Furthermore, both ends of the revolving door are fixedly provided with material guide plates perpendicular thereto, and the material guide plates are in contact with the inner wall of the material discharge box.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Because the second rotating shaft passes through the discharge box and is fixed with a second gear, a first gear is fixedly mounted on one of the fixed plates, meshing with the second gear. Therefore, when the rotating assembly drives the discharge box upward, the discharge box rotates the second rotating shaft, which in turn rotates the second gear. Since the second gear simultaneously meshes with the first gear, it rotates on its own, and the second gear, via the second rotating shaft, drives the revolving door downward, thereby opening it. Simultaneously, the discharge box also tilts upward, allowing the material inside to be dumped. This allows the revolving door to open simultaneously with the upward tilt of the discharge box, simplifying operation, achieving a high degree of automation, and increasing the speed of material dumping.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] For example 1, please refer to Figures 1 - 4 This embodiment provides a technical solution: an automatic feeder for processing plastic housings, comprising a feeder trolley 1. The feeder trolley 1 comprises a base plate, the bottom of which is evenly distributed with movable wheels, and a push handle fixedly mounted at one end of the base plate. A discharge box 2 is mounted on the base plate of the feeder trolley 1, and a support block is fixedly mounted on the bottom of the discharge box 2. The support block contacts the base plate of the feeder trolley 1 and is used to support the discharge box 2. Two symmetrically arranged fixed plates 4 are fixedly mounted on the top of the base plate of the feeder trolley 1, and a rotating assembly is mounted on the two fixed plates 4 to drive the discharge box 2 to rotate.

[0023] The rotating assembly includes a first rotating shaft 5, which is horizontally rotatably arranged between two fixed plates 4. A fixed block 10 is fixedly arranged on the outer periphery of the first rotating shaft 5, and the fixed block 10 is fixedly connected to the bottom of the discharge box 2. A motor 6 is fixedly installed on one of the fixed plates 4. The output end of the motor 6 passes through the corresponding fixed plate 4 and is coaxially fixedly connected to the first rotating shaft 5.

[0024] A rotary door 3 is movably arranged on one side of the feeding box 2 away from the pusher of the feeding cart 1. A second rotating shaft 9 is fixedly arranged at the bottom of the rotary door 3. The second rotating shaft 9 horizontally passes through the rotary door 3 and is rotationally connected to the feeding box 2. The second rotating shaft 9 passes through the feeding box 2 and is fixedly sleeved with a second gear 8. One side of one of the fixing plates 4 is fixedly provided with a fixed shaft, and a first gear 7 is fixedly sleeved on the fixed shaft. The first gear 7 meshes with the second gear 8. The axis of the fixed shaft coincides with the axis of the first rotating shaft 5, ensuring that when the feeding box 2 rotates around the first rotating shaft 5, the second rotating shaft 9 rotates around the first rotating shaft 5, so that the second gear 8 rotates around the outer circumference of the first gear 7, preventing the second gear 8 from disengaging from the first gear 7.

[0025] The diameter of the first gear 7 is larger than the diameter of the second gear 8, so that the angle when the feeding box 2 rotates upward is smaller than the opening angle of the rotary door 3. That is to say, the rotation speed of the second gear 8 is greater than the rotation speed of the first rotating shaft 5, thereby increasing the speed of pouring raw materials.

[0026] Guide plates perpendicular to the rotary door 3 are fixedly arranged at both ends of the rotary door 3. The guide plates are attached to the inner wall of the feeding box 2. When pouring raw materials, the guide plates can play a guiding role to prevent the raw materials from sliding out from both sides of the rotary door 3, thereby increasing the directivity when pouring raw materials.

[0027] The working principle of the automatic feeding machine for processing plastic outer shells provided in this embodiment is as follows:

[0028] After placing the raw materials in the feeding box 2, push the feeding cart 1 to send the raw materials to the required place. When pouring the raw materials, start the motor 6. The motor 6 drives the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the fixing block 10 to rotate. The fixing block 10 drives the feeding box 2 to rotate upward. The feeding box 2 drives the second rotating shaft 9 to rotate. The second rotating shaft 9 drives the second gear 8 to rotate around the first rotating shaft 5. The second gear 8 meshes with the first gear 7 at the same time, so that the second gear 8 rotates self. The second gear 8 drives the rotary door 3 to rotate downward through the second rotating shaft 9, thereby opening the rotary door 3. Since the feeding box 2 also rotates upward at the same time, the raw materials in the feeding box 2 can be poured.

[0029] Embodiment 2, please refer to Figures 5 - 6 , on the basis of Embodiment 1, this embodiment provides a technical solution: Two symmetrically arranged rectangular frames 12 are fixedly arranged on the top of the bottom plate of the feeding cart 1. A knocking block 13 is slidably sleeved in the rectangular block. A spring 14 is fixedly arranged between the knocking block 13 and the rectangular frame 12. A connecting block is fixedly arranged on one side of the knocking block 13. An avoidance groove is vertically opened on the rectangular frame 12 for avoiding the downward movement of the connecting block to prevent the rectangular frame 12 from hindering the downward movement of the connecting block.

[0030] On the outer periphery of the first rotating shaft 5, two symmetrically arranged toggle wheels 11 are fixedly sleeved, and the two toggle wheels 11 correspond to the two rectangular frames 12 one by one. A plurality of toggle blocks are fixedly arranged on the outer periphery of the toggle wheel 11 at uniform intervals, and one ends of the plurality of toggle blocks away from the first rotating shaft 5 are all arc-shaped. One ends of the plurality of toggle blocks in arc shape are respectively in sliding fit with the connecting blocks to drive the knocking block 13 to move downward.

[0031] The working principle of this embodiment is as follows:

[0032] When the first rotating shaft 5 rotates, the first rotating shaft 5 drives the toggle wheel 11 to rotate, the toggle wheel 11 drives the plurality of toggle blocks to rotate, and during the rotation of the plurality of toggle blocks, they are intermittently in sliding fit with the connecting blocks on the knocking block 13 to drive the knocking block 13 to intermittently move downward. The knocking block 13 moves downward to compress the spring 14. During the process when the previous toggle block disengages from the connecting block of the knocking block 13 and the next toggle block has not yet contacted the connecting block of the knocking block 13, the knocking block 13 moves upward under the restoring force of the spring 14 and knocks on the bottom of the feeding box 2, causing the feeding box 2 to vibrate, shaking off the raw materials adhering to the inner wall of the feeding box 2, and at the same time accelerating the speed of raw material pouring.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
